UI rewrite

[foobarbecue]

The UI was thrown together using direct dom manipulation. Eventually, it should be rewritten using a UI state object and one or more render functions. It might be worth using a UI framework like react, hyperapp or marko.

In a re-architechted UI I imagine we might have something like:

• Upper left corner layer switcher (default collapsed):
  • Maybe use https://github.com/walkermatt/ol-layerswitcher
• Upper right corner mosaic creation tools
• Lower right corner "drawer": Mosaic detail view
  • "at a glance" progress view
  • Raster tile view of mosaic if completed
• Lower left corner "drawer": Image detail view
  • Key stats
  • Raster tile view of image

Actually I'm thinking it would be good to do this with vanilla web components .
